PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 398,908, dated March 5,1889.

Application filed June 5, 1888. Serial No. 276,078. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE J STEVENS, of Bostomin the county ofSutfollnStat-e of Mas- 1 sachusett-s, have invented a certain new anduseful Improvement in Paper Bags, of which i the following is adescription sufficiently full, clear, and exact to enable any personskilled in the art or science to which said invention appertains to makeand use the same, reference being bad to the accompanying drawings,forming part of this specification, in which- Figure l is a plan view ofthe blank from which my improved bag is constructed, the side shownforming the outer side of the bag when folded; Fig. 2, a like View ofthe side opposite to that shown in Fig. l, or inner side of the bag;Fig. 3, a plan view similar to that shown in Fig. 2, and representingthe first fold in the process of forming the bag; Fig. 4, a sideelevation of the bag, the flaps and a pori tion of the bottom beingrepresented as unsecured; Fig. 5, a like View showing the bottom foldedand the flaps unsecured; Fig. 6, a perspective view of the finished baFig. 7, an enlarged vertical section taken on linexm in Fig. 6; andFigs. 8 and 9,perspective views showing a modification of myimprovement.

Like letters and figures of reference indicate corresponding parts inthe different figures of the drawings. v

My invention relates more especially to a paper bag having a double orre-enforced bot tom; and it consists in certain novel features, ashereinafter fully set forth and claimed, the 1 object being to produce asimpler, cheaper, and more desirable article of this character than isnow in ordinary use.

The nature and operation of the improvement will be readily understoodby all conversant with such matters from the following explanation.

In the drawings, A represents the blank, considered as a whole. Theblank is creased on two parallel transverse folding-lines, .2 r,dividing it into a body portion, B, and side pieces, D, and also on alongitudinal foldingline, 922, near its lower edge, dividing or settingoff bottom pieces, G H. The blank is cut diagonally from theintersection of each line .2 v with the line m across the piece H, asshown by the slits p in Fig. 1, to the lower edge thereof, formingtriangular [laps/'1 The outer side of the piece ll is coated withadhesive paste or cement, as shown at l) in Fig. 1,-the edge of theinner face of one side piece, D, and the inner faces of the bottompieces G and flaps f being also coated, as shown at (1 g 71,respectively, in Fig. 2.

In forming the bag from the blank A, as described, it is laid flat inthe position shown in Fig. 2 and the bottom piece H bent inward on theline on against the side portion, 13, assuming the position representedin Fig.3, its pasted side h being uppermost. The righthand side piece Dis then folded over the line o against the pasted side 71 of the bottompiece H, which adheres thereto. The left-h and side piece D is nextfolded in the same manner on the line .2 2, its pasted edge (I adheringto the edge of the opposite side piece D, thus holdin g them in positionand securing them to the bottom piece H, as shown in Fig. 7, the blankbeing then in the position shown in Fig. 4.

The bottom pieces G are next turned back on 7 5 the line on against theouter face of the body portion B, to which its pasted faces g adhere, asshown in Fig. 7, the blank being in the position shown in Fig. 5. Theflaps f are now bent on their lines o 2 against the outer faces of theside pieces D D and secured thereto by the pasted faces h, thus formingthe completed bag, as shown in Fig. 6.

It will readily be seen that by constructing the bag as described I amenabled to greatly strengthen it at the bottom, which is provided withtwo thicknesses of paper on each side thereof, as shown in 7, thusrendering it much more durable and less liable to tear than whenconstructed with three layers of paper at one side of the bottom and asingle thickness at the opposite side. Moreover, in my improved bagthere are no loose parts left in the interior of the bottom portion tocatch and retain the contents thereof, as sometimes 00- 5 ours in theuse of ordinary bags of this character.

In the modification shown in Figs. S and 9 the edges 'v z of the bag arebent inward to form a square side. flap, K, at each lower corner of thebag, which is pasted on its upper face and bent on a line against theside, where it is secured. This forms a bag which. is rectangular inshape,

This leaves a triangular 10o which greatly facilitates the fillingthereof, and, in addition, re=enforces or strengthens the lower cornersby the addition of said flaps.

Having thus explained my invention, what I claim is 1. The improvedblank for forming paper bags herein described, the same consisting of arectangular sheet; provided with two transverse creases or folding-iii]es which set off side pieces and a longitndimil crease or foldinglinewhich sets off bottom pieces, said blank being slit from theintersections of said creaselines diagonally across the center bottompiece, thus leaving a triangular flap on each outer bottom piece, andadapted to be folded and secured, subsiantiall y as set forth.

A paper bag consisting of the blank A, provided with the parallelcreases or foldinglines n 2', the longitudinal crease or folding"- line772, and the diagonal slits p, out from the points of intersection ofsaid lines, whereby the blank is divided into the body portion B,

side pieces, D,bottom pieces, G H, and flaps f, I

said bottom pieces, flaps, and side pieces being' secured together, sothat the bottom por- 2 5 tion of the bag is of equal double thicknessthroughout, substantially as set forth.

A paper bag coi'lsisting of a blank comprising the body portion B,provided with the bottom piece H and side pieces, D, having the 0 bottompieces i, provided with triangular flaps f, the bottom piece H beingpasted to the inner faces of said side pieces, the piece G pasted to theouter face of the body portion B, and the flaps f to the outer face ofsaid side 35
